It's in a single position where all of this is encapsulated, and on Sunday evening, Spain manager Vicente del Bosque put it into words.
"We have two days until I name my list of 23 players," he said at his post-match press conference following his team's 3-1 win over Bosnia and Herzegovina in Switzerland. "While we are waiting to hear from the medics, [Hector] Bellerin stays with us."
The medical team Del Bosque was referring to is the one evaluating Real Madrid's Dani Carvajal. The previous night in Milan, the right-back limped off at the San Siro during his team's victory over Atletico Madrid in the UEFA Champions League final, tears flowing in the fear of it—that not only would he miss the decisive period of the final, but that his Euro 2016 campaign might already be over too.
